configuration of RS modules, you require an 8004 or 8005 power supply. Do not mix 8004 and
8005 power supplies in the same chassis.

Power supply circuit requirements

The Avaya Ethernet Routing Switch 8800/8600 AC power supplies require single-phase source
AC.
Do not mix AC and DC power supplies in the same chassis.
The source AC can be out of phase between multiple power supplies in the same chassis.
Therefore, power supply 1 can operate from phase A, and power supply 2 can operate from
phase B.
The source AC can be out of phase between AC inputs on power supplies that are equipped
with multiple AC inputs. Therefore, power cord 1 can plug into phase A, and power cord 2 can
plug into phase B.
You can use the dual-input 8005DI AC power supply with two other single-phase AC sources of
different power feeds. To share the two power feeds with the dual input supply, connect the
AC source Power Feed 1 to input 1 on the dual-input supply, and then connect the AC source
Power Feed 2 to input 2 on the dual-input supply. Avaya recommends this configuration to
provide full power feed redundancy. See the following figure.
Figure 2: Dual-input power supply connections
On the 8005DI AC power supply, the two AC input sources can be out of synchronization with
each other, having a different voltage, frequency, phase rotation, and phase angle as long as
the power characteristics for each separate input AC source remain within the range of the
manufacturer's specifications.
